When I went to get him around 1:00 (I always let him play in his crib until he gets fussy), I found a very serious (and very wet!) little boy. I sat him up and took off his pjs, and I still can't figure out what he was thinking at the time. I'd hardly describe him as serious little boy, but he was that way the entire day!
Sometimes I play peek-a-boo with him through the crib slats, and we were doing that this afternoon. I can't remember if I got him smiling, but he was enjoying it.
Look at those beautiful brown eyes!
